Simplesonic

• minimalistic Subsonic server API implementation written in Go
• database free (browsing by folder structure)
• external go package free (using only standard library)
• jukebox support with MPD
• m3u support with extended directives
• tested on dsub, subsonic
• for a more feature-rich server, use: gonic, airsonic, or ampache

Configuration

Simplesonic config file (/etc/simplesonic/simplesonic.json or ~/.config/simplesonic/simplesonic.json)

{
  "server": {
    "listenAddress": ":4040"
    "tlsKey": "simplesonic.key"
    "tlsCert": "simplesonic.crt",
  },
  "musicFolders": [
    {

      "path": "/path/to/music"
    },

Generate self-signed TLS certificate

$ openssl genrsa -out simplesonic.key 2048
$ openssl req -new -x509 -sha256 -key simplesonic.key -out simplesonic.crt -days 3650

Minimal MPD config file (/etc/mpd.conf or ~/.config/mpd/mpd.conf)

Do not set db_file or music_directory!

bind_to_address    "/var/run/mpd.sock"

input {
        plugin     "curl"       
}

audio_output {                                                                                                                                                                                                                                                                              
        type       "alsa"
        name       "ALSA sound card"
}
